Having curved veins or nerves; especially used in botany to describe leaves with curved venation patterns.
From Latin 'curvus' (curved) and 'nervus' (nerve, vein) with the adjectival suffix '-ate'. This botanical term became standard in the 18th century when scientists began systematically classifying leaf structures.
Plant scientists can identify species just by looking at leaf veins—some plants have curved veins that help direct water flow downward, while others have straight ones, revealing how they've adapted to different rainy environments.
